Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support sleeve with many grooves and elevations is used for press fitting, then the sealing and compression capability is improved, but the manufacturing complexity increases significantly
Solution Approach 1:
The connecting piece is divided into functionally distinct areas: a sealing area with radial projections and sealing surfaces, and a holding area with simplified geometry. This segmentation allows each area to be optimized for its specific function while keeping the overall structure manufacturable.
Solution Approach 2:
The sealing area features localized radial projections and sealing surfaces that provide enhanced sealing capability only where needed, while the holding area maintains a simpler, more manufacturable geometry. This local differentiation resolves the contradiction by concentrating complexity only in the sealing function.
2Reliability
If a support sleeve with many projections is used, then the sealing performance is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The connecting piece is segmented into a sealing area with projections and a holding area without complex projections. This segmentation enables the sealing area to achieve reliable sealing through localized features while the holding area remains simple to manufacture.
Solution Approach 2:
Complex geometric features such as radial projections and sealing surfaces are applied locally only in the sealing area, while the holding area maintains a simpler, more manufacturable geometry. This local differentiation improves sealing performance without compromising manufacturing ease.
3Device complexity
If the sealing area and holding area are combined in one structure, then the device complexity is reduced, but the optimal design for each function is compromised
Solution Approach 1:
The connecting piece is segmented into a sealing area with radial projections optimized for sealing, and a holding area with simplified geometry optimized for mechanical load absorption. This functional segmentation ensures optimal design for each area while maintaining overall structural simplicity.
Solution Approach 2:
Each area of the connecting piece is given locally optimized properties: the sealing area has radial projections and sealing surfaces for optimal sealing, while the holding area has a simpler geometry for optimal load absorption. This local optimization resolves the contradiction between simplicity and functional performance.
4Ease of manufacture
If a single area serves both sealing and holding functions, then the manufacturing is simplified, but the sealing reliability under torque and longitudinal force deteriorates
Solution Approach 1:
The connecting piece is segmented into a sealing area with radial projections that maintain sealing under torque and longitudinal force, and a holding area that absorbs mechanical loads. This segmentation ensures sealing reliability while keeping the overall structure simple to manufacture.
Solution Approach 2:
The sealing area is given localized geometric features (radial projections, sealing surfaces) that ensure reliable sealing under various loads, while the holding area maintains a simpler geometry for load absorption. This local differentiation maintains sealing reliability without compromising manufacturing simplicity.

Implementation Method 1
Through the process of pressing the clamp ring, the pipe is pressed against the connecting piece, so that the contact surface of the connecting piece comes into contact with the inner pipe wall or is pressed against the inner pipe wall against the contact surface

AI summary
A pipe clamp (1) for connecting a pipe (2) comprises a connector (3) that can be inserted into the pipe (2) and has a front end (36) that projects into the pipe (2), and a clamping ring (4) that surrounds the connector (3) and the pipe (2) via an effective area (38) and can be compressed by a tool. The connector (3) comprises a side wall (17) extending substantially cylindrically around a central axis (M) with a contact surface (39) facing the inner wall (16) of the pipe. By compressing the clamping ring (4), the pipe (2) is pressed against the connector (3) so that the contact surface (39) of the connector (3) comes into contact with the said inner wall (16) of the pipe.The connecting piece includes in the effective area (38) of the clamping ring (4) a sealing area (70) for creating a seal between the connecting piece (3) and the pipe (2), as well as a holding area (80) designed separately from the sealing area (70) for receiving forces occurring between the connecting piece (3) and the pipe (2).
